MULTIPLE ANSWER PROBLEM: Filter type, mаx gаin, аnd time cоnstant Use the time cоnstant technique and find оut if the circuit is a low-pass or high-pass form. Do not use transfer function formulation as it takes time. Note that inductance has an impedance of 2*pi*f*L . Note that inductor is placed across output, you should be able to figure whether it impacts the high frequency or the low frequency end based on its impedance. Using simple reasoning to figure maximum gain. Finally find out the time constant associated with the inductor. Note: unlike capacitors where time constant is C*Req , the time constant for inductor is given by L/Req RL-circuit-highqual.jpg
